SPECIFICATION forming part of Letters Patent No. 406,418, dated July 9,1889.

Application filed April 11, 1887. Serial No. 234,466. (No model.)

To all whom it may concern:

Be it known that I, DAVID -WV. BASH, of Sandwich, in the county of DeKalb and State of Illinois, have invented certain new and usefulImprovements in Cultivators, of which the following is a full, clear,and exact description, reference being had to the accompany ingdrawings.

My presentinvention relates to an improvement in the cultivator patentedto me by Letters Patent No. 327,754, granted October 6, 1885. Itsobjects are to provide means whereby the gangs of blades maybe adjustedas a whole to better adapt them to pulverize and mellow slanting groundnear the growing plants; and also to pulverize the ground and move it toa greater or less extent to or from the plants; also to provide meansfor attaching the blades to the head, whereby the blades are capable ofbeing adjusted vertically and in the arc of. a circle; and also toprovide such means for connecting the beams to the culti valor-framethat the machine may be operated on crooked rows without altering theposition of the blades relative to the line of the draft.

To this end it consists in the construction and combination of partsherein described, and pointed out definitely in the claims.

In the drawings, Figure 1 is a perspective view of my improvedcultivator. Fig. 2 is a detail of the standard which connects the headsto the arch. Fig. 3 is a detail of one of the blades and the arm whichconnects it with the head.

As illustrated in the drawings, A represents the cultivator-frame, whichmay be of any suitable construction, and it is provided with meanswhereby the cultivator-beams may be pivotally connected therewith by avertical pivot-bolt a or otherwise, so that said beams are permitted toswing sidewise. The blades G are curved from shank to point in themanner common in this class of cultivators, and as shown in my formeratent. The heads B are provided with round sockets 1), into which therounded ends 3' of the arms J fit and are adapted to revolve. The bladesare secured to the flat rear ends j of said arms J by a bolt 9. Theblades are therefore capable of an adjustment in the are of a circle bypermitting said arms J to turn in the Sockets 1), and retaining them inthe proper position by a set-serewj which screws into the head B andagainst the rounded end j of said arm J. The blades are adjustedvertically by means of a set-bolt g, which passes through a slot 9preferably in the flattened rear end of the arm J, and is secured to theshank of the blade G. Ilhe blade turns on the bolt g as a pivot, and isheld in any desired position by tightening the nut on the bolt 9.

D D represent standards having arms d d, projecting substantially atright angles thereto to form a T-shaped head. One of the arms 01 ispivotally attached to said head by the bolt b, and the head is adaptedto oscillate substantially horizontally in the arc of a circle upon saidbolt, and means are provided for holding said head at any point to whichit is permitted to oscillate. The means provided are a slot (1' ineither the head or arm and a bolt 19 passing through said slot andsecured to the other of said parts, upon which a nut may be screwed tohold the parts in the relative position desired, The upright standards Dare adjustably secured to the ends of the arch E each by a pivot-bolt e,upon which the standard is permitted to oscillate, and thereby vary therelative vertical height of the ends of the heads B B. Means areprovided for holding the standard at any point in its oscillation, themeans shown being the slot 6 and set-bolt 8 By these means the-headswhich bear the blades are given two adjustments. That which results fromthe connection of the standard D with the arch E may be called a pivotaladjustment in a vertical direction, since it varies the relativevertical heights of the ends of the heads B, and adapts the machine tomellow the ground and cut the weeds upon the opposite slanting sides ofa row of plants, all of the blades being adapted to enter the groundsubstantially the same distance. The other adjustment, which resultsfrom the connection of the arms cl of the standard D with the head, maybe termed a pivotal adjustment in a horizontal direction, because thehead moves in a substantially horizontal plane, and as upon a pivot.This adjustment changes at once the angle at which all the blades lie tothe line of the draft. If that angle is increased with the form ofblades shown, their power to disturb and mellow the earth and move ittoward the rows is increased.

I do not mean, when I say that the two adjustment-s above described arepivotal, that the parts must necessarily swing upon the bolts shown toact as pivots or upon any fixed pivot-point. Both bolts may pass throughslots, so that the parts are movable at both points of connection, inwhich case they would move about an imaginary pivot between said points.

The cultivator-beams C are connected to the frame A at their forwardends by substantially vertical pivot-bolts a, and at their rear end tothe standards by a pivot-bolt c. F F represent the handles attached tothe heads, and by which said heads may be moved from side to side whenoperating upon a crooked row. Yv'hen they are so moved to one or theother side, the pivotal connection between the heads and drag-bars andthe arch, which rigidly connects said heads, compels the heads andblades to remain in the same relative position to the line of the draftas before such movement.

If the device were organized so that the connection between the headsand beams were rigid, a movement of the heads would cause the knives ofone gang to approach a position in line with the draft, while the knivesof the other gang would be placed more nearly at right angles thereto.

The above described device may be attached to any wheeled or walkingcultivator with nothing more than slight nonessential changes, and thedifferent parts of the invention, as claimed, may be used conjointly, asshown, or independently with other devices.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a cultivator, the combination of the heads provided with roundedsockets, arms having one end flattened and the other end rounded andadapted to fit in said sockets, and set-screws for retaining themtherein, with blades adj ustably secured to the flat tened end of saidarms, substantially as and for the purpose specified.

2. In a cultivator, the combination of the heads provided with roundedsockets, arms having one end flattened and the other end rounded andadapted to fit in said sockets, and set-screws for retaining themtherein, with blades pivoted to the flattened end of said arm, and aslot, bolt, and nut for securing said blade in any desired position,substantially as and for the purpose specified.

In a cultivator, the combination of suitable heads, and standardssecured thereto, with an arch having its ends pivotally connected withsaid standards, and means for rigidly securing the standards and archtogether, substantially as and for the purpose specified.

4. In a cultivator, the combination of suitable heads, each havingblades secured thereto, and an arch extending between said heads, withstandards, and adjustable connections between said standards and boththe arch and the heads, substantially as and for the purpose specified.

5. In a cultivator, the combination of suita ble heads and standardssecured thereto, an arch having its ends pivotally connected with saidstandards, and means for rigidly securing the standards and archtogether, with the frame and beams pivotally connected to both the frameand the heads, as and for the purpose set forth.

6. In a cultivator, the combination of suitable heads, each havingblades secured thereto, an arch extending between said heads, andstandards adjustably connected to both the arch and the head, with theframe and beams pivotally connected to both the frame and the heads,substantially as and for the purposes hereinbefore set forth.
